Specicaton of Letters Patent.

Application filed February 5. 1907. Serial No. 355.795.

To all whom it may concern:

Be it known that I, WILHELM SCHMITZ, subject of the German Emperor, and resident of N o. 33-34, Valentinskamp, Hamburg, Germany, have invented certain new and useful Improvements in an Incandescent Gas- Burner, ofwhich the following is a specification.

Object of the present invention is a flue with a cooling device, for inverted incandescent gas-burners, which has the purpose of conducting fresh air continually into the burner so that the gases and the particles of smoke which rise are taken off and distributed to one direction by which means the said gases and smoke'cannot touch the illuminating body.

The flue consists of a shell like cap which is provided with deep undulated walls.

The accompanying drawing shows a form of construction of the invention in two figures.

Figure l is a side view of the flue projecting from the burner. Fig. 2 is a front view of the same.

The iiue a is provided with channels b and the slits c for allowing the gases and smoke which rise to distribute themselves, after the combustion, into the channels b ofthe flue Patented Jan. 28, 1908.

tially projecting from the burnerso as to be adapted to cool the rising hot gases in the folds thereof, and the said flue having longitudinal openings at the sides horizontally for letting the outer air go into the inner folds of the flue cool and withdraw the rising hot gases, substantially as described.

Dated this 27th day of June, 1907.

WILHELM SCHMITZ.
